JOSEPH C. SILVY, OF NEW ORLEANS, LOUISIANA, ASSIGNOR TO T. J. DOBYNS, OFNEW ORLEANS, LOUISIANA.

FOUNTAIN-PEN.

Specification of Letters Patent No. 16,514, dated January 2.7', 1857.

` To all whom it may concern."

Be it known that I, JOSEPH C. SUNY, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a certain new and usefulImprovement in Ink-Pencils, f which the following is a full, clear, andexact description, reference being had to the accompanying drawing,which forms part of this specification, and in which the ink-pencil asimproved by me is shown in whole in section and in detail, as will behereinafter described.

My improvement hasv reference to the device described in the patent ofE. Jordan of 20th November 1849, in which, a hollow handle forcontaining ink, conically sharpened at the point and pro-vided with aloose guide rod for the ink (projecting partly through said point andacting as a stopper 'to the How) is used; the pressure of the infectiveowing t-o the want of promptness inV action of the central rod to openand shut 0E the flow, the tendency of the rod to stick by the lateralthrust thrown upon it in writing, its liability to bend and wedge andits light character causing it to fail when required to drop, to riseonly upon great and unequal downward pressure being exerted, or else tobe so slow and dead in these necessary actions of rising and fallingwhen writing as to cause it to drag, scratch and be so devoid of thatfluency or freedom which a writing pencil should have equally with orinlike manner to a good writing pen, and, lacking which, this pencilform of writing instrument, that has many conveniences and advantagesover a pen form of instrument and is not identical with it, hasheretofore-and in the form in which I have described it upon which myimprovement is based-failed to become generally adopted or to beregarded even as a practical thing.

To render such device practicable and perfect in its action is theobject of my improvement, and that this is accomplished will be obviousfrom the following brief description taken in connection with thepreceding allusions to present defects.

A, in the accompanying drawing, represents the pencil complete, chargedwith ink and ready for use; E a shield that may be slipped over thepointed end of the pencil to protect the point when the instrument isnot being used.

B is a longitudinal sectional view of the pencil entire; and C thecentral guide rod to conduct the ink around it out of the reservoir orhandle to the point and sharpened at its end and reduced so as to form avalve or stopper at the point of the instrument for operation in themanner and for the purposes described. This guide rod (C) extends upwardand is armed with a spiral spring which not only serves to press downthe rod promptly so as to shut oif the flow from the point whenwithdrawing the instrument from use, but to regulate the iiow in the actof writing with the greatest softness, ease, and nicety, according tothe pressure thrown upon the projecting point of the stopper or guiderod in its bearing on the paper; and serves to give that fluency andfreedom of action to the guide rod which enables it, when writing, tooperate quickly, prevents its sticking, dragging or scratching and makesthe instrument, heretofore impracticable or diiiicult to use,practicable and easy to use. This spring is shown as arranged between abutton at the head of the guide rod and that serves to keep the guiderod true, and a transverse piece or disk in a cap D which screws uponthe top of the instrument when the instrument is charged with ink, asshown in figure B of the drawing.

What I claim as my improvement upon the ink pencil described in thepatent of E. Jo-rdan of 20th November, 1349, and desire to secure byLetters Patent, isf- The employment of a separate or independent springto the guide or stopper rod for operation with it and the pointedfountain case or handle as shown and described and for the purposesspecified.
